STANDING-VALVE rULLrn.`

Application filed October 23, 1926. Serial No. 143,716. y.

,ln standing valve pullers heretofore used the coupling members'on the .plunger and standing valve were rigidly connected to their respectivemembers, and this construction resulted in serious damage to the said coupling members when the plunger would strike against the standing valve.

An object of my invention is to provide a yieldable puller for the standing valve of Cil ' the puller in engaging Fig. 8 is longitudinal sectional view of appump.

Another object is to provide a yieldable puller which will also actto control the balls in the pump valves. y A. Afurther object is to provide a puller which will be positively engaged by the so that they standing valve pump plunger the well afterit is once cannot fall back into engaged. y

Other objects, advantages and features of invention may appear from the accompanying drawing. subjoined detailed description, the appended claims or in the operation of niv device.

ln the drawing: Fig. 1 is a longitudinal sectional view of my puller.

Figl 2 is a longitudinal sectional view of position. f

a iiiodilied forni of puller.

Fig. 4 is a plan view of the puller sleeve. Fig. 5 is a plan view of the tube which is secured Yto the pump plunger.

Referring more particularly to the drawf ing:

My invention is applicable pump construction including barrel 1, the plunger' 2 and valve 3. A square post 4 rises from the standing valve 3 and is threaded in the top thereof, said post having a head 5 formed on the top thereof. A sleeve 6 is slidably mounted on the square post 4 and a spring 7 surrounds said post and yieldably urges said The sleeve-6 is formed to the usual the working the wing S being greater in width than the wing 9, the purpose of which will be further described. Y

A tube 10 screws into' the lower end of the plunger 2 and depends therefrom. It is desirable under certain conditions that a valve such as the one shown at 11 be positioned in the lower end of the plunger 2. The top of the tube 10 is provided with an opening 12 therein, said opening conforming in shape Yagainst the urge of the spring Ain the extreme lower position the standing kto the sleeve 6, thusl it will be seen that in one position only will the sleeve 6 enter the opening 12. In operation the plunger 2 is reciprocated in the working barrel, in the lmanner welly known to the art and if the tube 10 should engage the sleeve 6, said sleeve will merely slide downwardly on the post 4 7 and will cause no damage to the` engaging parts.

Vhen it is desired to pull the standing valve, the plunger 2 is llowered 'until the tube 10 rests on the standing valve as shown in Fig. 2. In this position the spring 7 is compressedand urges the sleeve 6 upwardly. Upon rotationv of the plunger 2 the opening 12 willregister with the sleeve 6 and the spring will then urgethe said sleeve upwardly to the position shown in dotted lines, Fig. 2. A slight reverse turnpof the plunger 2 will then securely lock the sleeve 6 in position over the tube 10, and the standing valve may be pulled. v

Wien a lower valve 11 is used as shown in Fig. 1 the post- 4 will extend upwardly through the opening 12, unseating the ball 13 of the plunger; thus insuring the proper operation of the valve. As shown in Fig. 3 the square post 14 is slidably mounted in the top of the standing valve 3 and a spring 15, acting against a lcollar 16 normally holds said post in raisedposition. The sleeve 6 as previously described as sli d ably mounted on the square post 14 and a spring 17 normally urges said sleeve upwardly against the tube 10. It will be evident that in the lowered position of the plunger the top of thetube 10 will engage the sleeve 6. compressing the springs 15, 17 and urging the lower head 18 of the post 14 against the standing valve ball 19; thus positively seating said ball and, simultaneously the top head 2O will engage the ball 13 of the valve 11, unseating saidv last named ball. Thus at each stroke of the plunger the standing and traveling valves are positively actuated.

f Havingl described my invention. I claim:

1. In a pump comprising a standing valve and a plunger, a post rising from said standing valve, a-sleeve vieldably mounted'on said posti` and means on said plunger adapted to engage said sleeveawhereby the standing Y valve may vbe pulled.

2. In a pump comprising afstanding valve and a plunger, a post rising from said standing valve, a sleeve yielda-bly mounted on said post, a tube depending from said plunger, said tube having an opening therein, adapted to receive said sleeve; whereby the standing valve may be pulled. Y y

3. In a pump comprising a standing valve and a plunger, a pest rising trom said stand'- ing valve, a sleeve slidably and nonrotatably mounted on said post, a spring engaging said sleeve, a tube depending from said plunger, said tube having an opening therein, adapt ed to receive said sleeve.

.4. In a pumpeemprising a standing valve and a plunger', a post rising from said standing valve, av sleeve slidably and nonrotatably mounted on said post, a spring engaging said sleeve, a tube depending from said plunger, said tube having an openingl therein, adapted to receive said sleeve, said sleeve being' formed with outwardly extending Wings, one of eaid wings being greater in Width than the other, and said opening being'the same shape as said sleeve. u

5. In a pump Comprising a standing valve and a plunger, a post slidably mounted in said standing valve, means holding said post in a normal raised position, a sleeve on said post, resilient means engaging said sleeve and means on said plunger adapted to engage said sleeve; said post being adapted to engage the ball in said standing valve in the lowered position of the plunger.

6. In a pump comprising a standing valve and a plunger, a post slidably mounted in said standing valve, a spring normally urging said post' to a raised position, a sleeve i on said post, a spring engagingsaid sleeve, a tube depending from said plunger, said tube having an opening therein, adapted to receive said sleeve; whereby the standing'- valve may be pulled, said post being adapted to engage the ball vin said standing valve inthe lowered position of the plunger.

7. In a. pump comprising a standing valve, a plunger and a valve in the lower part of said plunger, a post slidably mounted in said standing valve, a sleeve slidably mounted ou said post, 'resilientmeans engaging said sleeve, means on said plunger adapted to engage said sleeve, said post being adapted to engage the balls in the standing valve and plunger valve in the lowered Vposition of said plunger.

lIn testimony whereof, I afliX my signature.
